25654BA Audemars Piguet Royal Oak Perpetual

25654BA-Audemars-Piguet-Royal-Oak-Perpetual

While the Royal Oak was intended to be a time-only sports watch, its abilities quickly diversified after the 5402 with a range complications. The most iconic of these must be the Quantieme Perpetual (or perpetual calendar moonphase to us peasants). It is a beautifully contrasted blend of sporting pretense and haute watchmaking that, before the…

3940P Patek Philippe Perpetual Calendar

3940P-Patek-Philippe-Perpetual-Calendar

When John Reardon states that ‘for the price, there is arguably no other watch that encapsulates all that defines Patek Philippe’, you listen. In gross understatement, the man knows Patek Philippe. Further, when nearly every notable collector starts referring to the 3940 as Patek’s quintessential calendar, you know we are at the outset of a…

4th Series 3970EP Patek Philippe Perpetual Calendar Chronograph

4th-Series-3970P-Patek-Philippe-Perpetual-Calendar-Chronograph

Patek’s 3970 has enjoyed one of the sharpest upward trajectories in collectability of anything this side of a Cosmograph in recent years.

5495 Blancpain Villeret Platinum Perpetual

5495-Blancpain-Villeret-Platinum-Perpetual-Calendar

Nineties Blancpain is a distinct beast entirely, from all of horology. Famously, toward the ceasefire of the quartz crisis, Blancpain ran ads claiming ‘since 1735, Blancpain has never produced a quartz watch and we never will.’ Blancpain and Jean-Claude Biver may not have quite singlehanded dragged Swiss mechanical watchmaking into the modern era, but that…

First Series Beyer 3940J Patek Philippe Perpetual Calendar

Beyer-3940J-Patek-Philippe-First-Series

Patek’s 3940 was released unto the world during troubled times as a bold step toward the modern era. When Philippe Stern chose to celebrate mechanical complication at the dawn of Patek’s future, he did so with the help of his close friend, Theodore Beyer.

First Series 43031 Vacheron Constantin Perpetual Calendar

43031-Vacheron-Constantin-Perpetual-Calendar-First-Series

The 222 is not VC’s only reference forgotten to the evolution time, now only known to enthusiasts. The phrase ‘post-quartz perpetual’ brings to mind almost exclusively AP’s 5548, debuted in 1978. However, just a hair behind (in terms of investment in time it takes to develop an in-house, ultra-thin perpetual calendar), were VC with this…

Green De Bethune DB25QP Perpetual

De-Bethune-DB25QP-Perpetual-Calendar-Green

Insanely technical independent De Bethune are perhaps best known for their use (or misuse) of the pun Starry Varius or insane lug designs. The manufacture is an involved one, one of the few independents that manufacture everything from the hairspring to the handset vertically. Outside of heat blued titanium, they are not closely associated with…
